The leaves of 'Red Siam' are broad, lance-shaped, and glossy, growing on short upright stems from a central base. Each leaf is deep green along the edges and shifts to vivid red and pink toward the center, with the color intensity varying by light exposure. The plant typically reaches 18 to 24 inches tall indoors, with leaves that can span 6 to 8 inches across.
'Red Siam' is grown primarily for its foliage rather than its flowers, and mature plants can occasionally produce small, spathe-type blooms similar to other aroids, though these are modest and not fragrant. It pulls double duty as an air purifying plant, filtering formaldehyde and other airborne toxins from indoor spaces. It wilts slightly when dry, and the soil surface turning pale and powdery is another cue that water is due.
Keep 'Red Siam' away from south-facing windows, where direct sun exposure scorches the leaves. It grows well under standard office fluorescent or LED lighting, and it also thrives near a kitchen where ambient moisture stays higher. Cats, dogs, and small children should not have access to the plant, as the sap causes skin and paw irritation and the plant is harmful if ingested. A high shelf or a room that small children and pets cannot enter freely are the safest placement options.
Chinese Evergreen 'Red Siam' grows well in medium to bright indirect light, away from direct sun exposure.
Water it every 10 to 14 days, allowing the top inch of soil to dry out between waterings.
'Red Siam' does best in a well-draining mix of potting soil combined with perlite or coarse sand.
It prefers temperatures between 65°F and 80°F and should stay away from cold drafts, air conditioning vents, and heating units.
It is hardy in USDA zones 10 to 12, tolerating outdoor conditions only where temperatures stay above 50°F year-round. It grows outdoors in Florida, Hawaii, and the warmest parts of California and Texas. It performs best as a permanent outdoor plant in frost-free areas of Louisiana, Arizona, and southern Georgia.
Q: How much light does Chinese Evergreen 'Red Siam' need indoors?
A: A north or east-facing window works well.
Q: How do I know if I'm overwatering?
A: Chinese Evergreen 'Red Siam' will develop yellowing lower leaves and soggy soil when overwatered. If the roots sit in wet soil too long, they begin to rot, so always check that the top inch of soil is dry before watering again.
Q: Is 'Red Siam' safe around pets?
A: Cats and dogs should be kept away from it. The sap causes skin and paw irritation on contact, and the plant is harmful if eaten. Keep it on a high shelf out of reach.
Q: Can I leave this plant alone for a week or two while traveling?
A: 'Red Siam' can go up to ten days without water. Water it thoroughly just before you leave and place it away from direct heat sources.
Q: Does Chinese Evergreen need high humidity indoors?
A: It does prefer higher humidity and may benefit from placement near a kitchen or bathroom. Avoid positioning it directly in front of an air conditioner or heater vent, as the dry blowing air dries out the leaves faster.
Q: Can I bring this plant outdoors in summer?
A: Chinese Evergreen can move outside during summer months in a shaded or partly shaded spot. It needs protection from rain, as heavy downpours can damage the leaves and saturate the soil.

🌿 For Houseplants
When your package arrives, you may notice a bit of loose soil in the box. This is completely normal during shipping.
Please remove your plants from their packaging as soon as possible and review the care instructions included with your order. Water based on your plant’s needs, making sure not to overwater.
Houseplants may need a short adjustment period after arrival. Give your plant time to acclimate to its new space before placing it with other plants. You can gently clean the leaves if needed, and wait to fertilize until it has settled in. Always check soil moisture instead of watering on a fixed schedule.
*** We pack carefully to protect each plant during transit, so larger orders may arrive in multiple packages.
